I want to know how many compression rate can be realized in the video lossless compression. This product is used in Hd video surveillance area.
Compression ratio of lossless depends entirely on the content. On average it will be around 2:1 but it could be much higher for very simple images and could actually be worse than 1:1 if the image was random noise.
Thanks. The ADV212 implements JPEG2000-compatible viedo CODEC. Does it mean that the compression ratio of lossless is also decided by the standard of JPEG2000?
For lossless, that is certainly true. All compressors will do it the same way.
